Abstract

A hydraulic screw machine having a housing employing a screw assembly with a drive screw and cooperating idler screws. The drive screw is sealably connected to a shaft extending beyond the housing on the high pressure side and has associated therewith a balance piston for acting on the screw drive. The drive screw is journalled to the shaft via bearings in the form of a self-adjusting plate surrounding the shaft. The plate is disposed between abutment surfaces connected to the housing for limiting its axial movement. A leakage channel between the piston and the housing is connected to the high pressure side of the machine and is determined by the balance piston.
